Ranking methodology
Each agency is assessed against the same eleven criteria, based on public information about it (its official website, its offer, pricing and case study pages, its guides, its event pages, its legal notice) and on reviews published on Google and Trustpilot, collected on 23 October 2026. datashake, the parent company of the site’s publisher and a sponsored feature, was assessed on 25 October 2026 based on its public information and on information it provided for this ranking. The first three criteria are common to all Journal Marketing agency rankings; the other eight are chosen for this ranking, including the last four, specific to WordPress SEO. Players publishing a WordPress SEO offer or method are included, as well as datashake, whose WordPress SEO offer was provided for this ranking.
